FRED WALTHER, OF OMAHA, NEBRASKA.

INTERNAL-COMBUSTION-ENGINE WATER-HEATER.

Specification of Letters Patent.

Patented Jan. 6, 1920.

Application filed December 5, 1918. Serial No. 265,433.

To all whom it may concern Be it known that I, FRED IVALTHER, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented new and useful Improvements in Internal-Combustion-Engine lVater-Heaters, of which the following is a specification.

My present invention pertains to heaters for automobile radiators and it contemplates the provision of a device of the character set forth that will so heat the water contained in the radiator that the engine may be easily and quickly started in cold weather thereby reducing the consumption of gasolene, and one through the use of which water will not freeze in the radiator, enabling the owner of the automobile to store same in a garage or other building notwithstanding the temperature may be down to the zero point.

With this and other objects in view, the invention will be fully understood from the following description and claims when the same are read in connection with the drawings accompanying and forming part of this invention, in which:

Figure 1, is a section taken through my novel heater and showing the heating unit I desire to employ and,

Fig. 2, is a view illustrating the manner in which the heater is attached to an automobile radiator.

Similar numerals of reference designate corresponding parts in both views of the drawings.

My novel heater comprises a heating unit 1, as clearly shown in Fig. 1, havlng a threaded porcelain core over which a very fine German silver thread is wound with its ends connected with a flexible wire 3, which in turn is covered with glass beads i, so as to prevent short circuiting of the wires 3. At this point, I would have it understood that the wires may be covered with asbestos or other non-inflammable matter;

At 6, is illustrated the brass tubing I employ to inclose the wire; said tubing being seamless and closed at one end by a brass disk 7, formed by overlapping of said tubing and at its other end said tubing is closed by a porcelain plug 5 having apertures for the reception of the wires 3.

It will here be noted that the said plug 5, is retained in place by the overlapping of the tubing end.

As clearly appears in Fig. l, the heating unit is rigidly soldered in a jacket 8 of brass or other material, said jacket being drilled at the larger outlet for the heating unit, while the smaller outlet is drilled and tapped for a inch standard pipe.

So as to exclude loss of heat, this jacket is provided with a sectional asbestos covering 9, and is held in proper position by two band rings 10.

As clearly appears in Fig. 2, the control board 11, may be provided with double pole fuses 12, with a three way switch 13, pilot lamp 14 with a resistance 15. This control may be employed to assist the operator in applying current to the heating unit, but I would have it understood that any other system may be used, such for instance, as a simple extension cord, having male and female members which may be easily used on any lighting system.

In the use of my invention, the heater is applied to the radiator by removing the well-known drip-cock located at the lowest part of the radiator and attaching the heater to the outlet 20, through the means of the reducing bushing 21, and then the dripcock 22 is screwed into the base of my novel heater.

It will be readily seen that my novel device may be easily and quickly attached to any make of car, in a few minutes, without alterations to the car.

Having described my invention, what I claim and desire to secure by Letters Patent is:

1. A device of the character described, comprising an electric heater suspended horizontally from the bottom of an automobile radiator, said heater consisting of a heating unit inclosed within a case, said case being rigidly secured within a heat insulating jacket and closed at one end by a disk which is overlapped by the end of the case, and closed at its other end by an insulating plug retained in position by the lapping of the other end of the case, and terminal wires fitting in apertures formed through the plug, said wires being covered with non-inflammable material and terminating at a source of electric energy for supplying current to the heating unit.

2. A device of the character described, comprising an electric heater adapted to be mounted in a position horizontally below an automobile radiator, said heater consisting of a heating unit, inclosed Within a said heating unit when attached to the 10 case, an insulated heat jacket surrounding proper source of electric energy.

said case and unit rigidly secured to the In testimony whereof I have hereunto set case and provided With an inlet and outmy hand in presence of two subscribing Witlet, said case being closed by a disk at one mes esend and closed at its other end by a plug FRED WALTHER. retained by the overlapping of the other Witnesses: end, and terminal Wires emanating from the D. B. MARSHALL,

plug and capable of supplying current to C. M. HANSEN.
